#2321: mpich-3.2 is not valgrind clean with petsc examples
-------------------+-------------------
 Reporter:  balay  |       Type:  bug
   Status:  new    |   Priority:  major
Milestone:         |  Component:  mpich
 Keywords:         |
-------------------+-------------------
 When petsc switched from 3.1.3 to 3.2 - we started seeing valgrind
 messages from MPICH.

 Could you take a look at this? I can help with running petsc examples that
 produce these messages.

 valgrind clean log with mpich-3.1.3
